George-Petru Ciordas-Hertel is currently working in the Educational Technologies Group at DIPF | Leibniz Institute for Research and Information in Education in Frankfurt am Main (Germany). After studying computer science at the Technical University of Darmstadt, he started his career as a professional software engineer and worked on a wide variety of projects for seven years, focusing on software architecture and AI assistance. In his research, he develops scalable software infrastructures and uses AI methods to evaluate the impact of diverse environmental factors on learning processes and the learners. His current research is focused on mobile sensing of learners' physical and digital learning contexts with smart wearables for learning analytics. Here, his emphasis is on evaluating the impact of self-initiated distractions with and external distractions from smartphones on learning behavior in online learning platforms. In addition, he addresses privacy requirements in the use of multimodal learning sources.
